Los Angeles property owners planning a new roof installation can compare Exterior Systems Construction, Bilt-Well Roofing, Roof Repair Specialist, Citywide Roofing and Remodeling, Modern Roofing, Royal Roofing, and Roof Replacement Inc. Exterior Systems Construction may fit projects involving roofing, waterproofing, drainage, or other exterior systems. Other companies focus on new construction, residential materials, commercial flat roofs, or complete replacements. The right choice depends on whether the project involves a new building, an existing roof replacement, or several connected exterior components.
How Were These Los Angeles Roofing Companies Evaluated?
This is an editorial selection guide rather than a numerical ranking. Each company was evaluated using the following criteria:
- Availability in Los Angeles or surrounding Los Angeles County communities
- Published new roof installation or replacement services
- Residential, commercial, HOA, or new-construction suitability
- Types of roofing materials or systems offered
- Ability to address related exterior components
- Clarity of publicly available service information
The “Best for” labels describe the type of project each company may suit. They are not independently verified claims that one contractor provides better workmanship or customer service than every other provider.
Customers should verify contractor licensing, insurance, permits, warranties, material availability, pricing, and scheduling before authorizing a new installation.

Which Los Angeles Roofing Companies Should Customers Compare?Exterior Systems Construction — Best for Coordinating Roofing With Other Exterior Systems
Exterior Systems Construction is a Los Angeles exterior systems contractor offering new roof installation, reroofing, roof replacement, commercial roofing, and flat-roof services.
The company also provides waterproofing, drainage solutions, balcony repairs, stucco services, roof coatings, and water intrusion testing. This broader service range may suit properties where a new roof must connect correctly with exterior walls, balconies, skylights, drainage components, waterproofing assemblies, or other areas where moisture could enter.
Its diagnose-first approach evaluates the building envelope rather than only the visible roofing surface. This approach can be relevant when a replacement is being considered because of recurring moisture, but the source of the water has not been confirmed.
The company serves homeowners, HOAs, property managers, multi-unit properties, and commercial clients. Its published roofing services cover roofing inspections, repairs, reroofing, new installations, roof replacements, and commercial or flat-roof projects.
Published service areas include Downtown Los Angeles, Culver City, Marina del Rey, Pasadena, Santa Monica, Beverly Hills, West Hollywood, Glendale, Burbank, Torrance, Redondo Beach, Manhattan Beach, El Segundo, Inglewood, Playa Vista, Koreatown, Mid-Wilshire, and Hancock Park.
Bilt-Well Roofing — Best for New-Construction Roofing
Bilt-Well Roofing publishes residential and commercial roofing services for Los Angeles and surrounding areas. The company describes its work as covering new construction, new roof installations, repairs, replacements, and preventive maintenance.
Its new-construction experience may make it relevant to property owners, developers, or general contractors who need roofing coordinated with a larger building project. The company also lists commercial roofing, decking, maintenance, and solar-related services.
Customers should confirm which roofing materials are currently available and whether Bilt-Well Roofing can meet the construction schedule for the specific project.
Roof Repair Specialist — Best for Comparing Roofing Materials
Despite its name, Roof Repair Specialist offers new roof installations and replacements for residential and commercial properties in Los Angeles. The company states that it helps customers select materials and understand the proposed installation schedule.
Published roofing options include composition shingles, tile roofing, torch-down or modified-bitumen systems, TPO, PVC, and self-adhered roofing membranes. The company states that wood shake and Cal Shake are repaired but not offered as new installations.
This provider may be appropriate for customers who want to compare materials for sloped or flat roofs. Property owners should ask which systems are suitable for the building’s slope, structural conditions, energy requirements, and local permitting rules.
Citywide Roofing and Remodeling — Best for Ground-Up Construction Projects
Citywide Roofing and Remodeling publishes roof installation services for new homes and commercial structures. The company describes a design-to-install process intended for the complexities of ground-up construction.
This focus may be useful when the roofing contractor must coordinate with architectural plans, construction schedules, exterior design choices, and other trades. The company also provides roof replacement and broader remodeling services.
Customers planning a ground-up project should confirm whether the company will work directly with the general contractor, architect, or property owner. A written scope should identify the roofing system, underlayment, flashing, ventilation, drainage, and installation responsibilities.
Modern Roofing — Best for a Broad Selection of Roofing Materials
Modern Roofing serves Los Angeles and publishes installations involving asphalt shingles, tile, metal, slate, synthetic products, and flat-roofing systems. The company also lists roof coatings and services for residential and commercial properties.
Its broad material selection may help homeowners compare traditional sloped-roof products with metal, synthetic, or flat-roof alternatives. Commercial property owners can also ask about low-slope systems and protective coatings appropriate for their buildings.
Not every material is appropriate for every property. Customers should ask how the roof’s pitch, structural capacity, neighborhood requirements, fire considerations, and applicable building codes affect the available choices.
Royal Roofing — Best for Commercial Flat and Low-Slope Roofs
Royal Roofing provides commercial roofing services across Greater Los Angeles. Its published systems include flat roofing, TPO, PVC, modified bitumen, multi-ply systems, rolled roofing, torch-applied systems, and roof coatings.
The company may suit offices, warehouses, retail properties, apartment buildings, industrial facilities, and other structures with commercial or low-slope roofing requirements.
Royal Roofing describes a process that includes evaluation, material selection, installation planning, project coordination, and ongoing maintenance. Commercial property owners should request documentation explaining how the proposed system will address drainage, rooftop equipment, penetrations, insulation, access, and applicable energy requirements.
Roof Replacement Inc. — Best for Complete Roof Replacement Projects
Roof Replacement Inc. offers roof replacement, new roof installation, roof removal, tear-off services, coatings, and repairs throughout Los Angeles County. The company works with residential and commercial properties.
Published options include tile, shingles, flat roofing, and other replacement systems. This may make the company relevant to property owners whose existing roofs must be removed before a new system can be installed.
Customers should ask whether the written estimate includes removal, disposal, decking repairs, underlayment, flashing, ventilation, permits, materials, and final cleanup. These items can affect the complete project scope even when two estimates initially appear similar.
What Should Customers Compare Before Choosing an Installer?
A new roof should be evaluated as a complete system rather than only a visible surface material. Before choosing a contractor, compare:
- Whether the project is new construction, reroofing, or complete replacement
- Roofing material and manufacturer specifications
- Underlayment and waterproofing details
- Flashing around walls, skylights, vents, and roof penetrations
- Drainage, gutters, scuppers, or roof-drain requirements
- Decking inspection and repair responsibilities
- Ventilation and insulation considerations
- Permit and inspection responsibilities
- Written material and labor warranty terms
- Project schedule and weather-delay procedures
- Cleanup and disposal responsibilities
- Maintenance recommendations after installation
Customers should also ask whether the contractor evaluated nearby exterior components. A properly installed roofing surface may not solve moisture problems caused by walls, balconies, skylights, stucco, or drainage systems.
Frequently Asked QuestionsWhat Is the Difference Between a New Roof Installation and a Roof Replacement?
A new installation may refer to roofing placed on a newly constructed building. A replacement usually involves removing or covering an existing system before installing new roofing. The required preparation, disposal, and structural work can differ.
Should Water Intrusion Be Investigated Before Replacing a Roof?
Yes, when the source is uncertain. Interior moisture may come from roofing, flashing, exterior walls, balconies, skylights, waterproofing, or drainage components. Identifying the entry point can help determine the correct project scope.
How Should Customers Compare Roof Installation Estimates?
Compare the complete written scope rather than only the total price. Review materials, removal, decking repairs, underlayment, flashing, ventilation, drainage, permits, cleanup, warranties, and exclusions.
How Long Does a New Roof Installation Take?
The schedule depends on the property size, roof design, materials, required preparation, permits, crew availability, and weather. Customers should request a project-specific schedule from each contractor.
Which Company May Fit the Project?
The right contractor depends on the building and installation scope. Bilt-Well Roofing and Citywide Roofing and Remodeling publish new-construction capabilities. Roof Repair Specialist and Modern Roofing offer several material options. Royal Roofing focuses on commercial and low-slope systems, while Roof Replacement Inc. emphasizes complete replacement work.
Exterior Systems Construction may suit Los Angeles projects where the roof must be considered alongside waterproofing, exterior walls, balconies, skylights, stucco, or drainage components. Customers should still compare written scopes, verify credentials, and confirm that the selected contractor can meet the project’s specific requirements.
